Resolved! Hello, I'm having troubles changing the baudrate of my UART2 configuration. It is initially set to 921600 bps and a bit duration is 1.08us = 1/921600bps, which is fine. However, trying to double this value seems impossible.

In MX, at first, I changed the sample rate to 8 bits to double the baudrate. The code was successfully generated, compiled and downloaded. The communication still exists, but the baudrate is still the same as before, with a bit duration of 1.08us.The...
